I've tried duplicating the layer, masking it and moving it over while keyframing the mask. The end result looks like the salt flats are slightly swimming. I've also tried mocha but the camera move is quite long and the result enlarges the clean plate too much.
I got about a .8 rms error in syntheyes for the second half of the shot so I think this is the way to go. Any ideas?
mochaPro has the Remove Module. The shot isn't as bad as I had imagined. However, the lens flare may interfere with the tracking engine. Multiple clean plates will be ideal as mentioned in an earlier post but you will find it incredibly difficult to match the clean plates due to the patterned floor.
There are just too many things wrong with the clip from a production POV. My thoughts are that tracking wasn't thought out as a requirement when this was shot.
I suggest that you check this out with the good folks at Imagineer's forum on their site.

But otherwise, you need to make a synthetic plate (2D) that is basically an overhead view of the land that needs to be painted out, and paint out the tracks on this one static layer.
Then track the shot using a 3D or 2.5 D tracker
Orient the synthetic element to match the real ground.
Use a mask to reveal the synthetic element.
Put the main plate on a layer above, and use Multiply to add the shadows back in as necessary.
You can probably ADD in back the lens flares using a layer of the main plate, or use a plug in to add in a simulated flare to cover.
You can do this with Mocha AE for the 2.5D track, use Photoshop for the synthetic plate, and create the masks in Mocha or in AE. However, I think you'd be happier with a 3D track for the synthetic replacement element.
